The phrase comes from Fist of the North Star, the 1980s manga and anime series known in Japanese as Hokuto no Ken, where martial artist Kenshiro tells defeated opponents they are already dead after striking their pressure points. Clips of the line spread widely as a meme in the 2010s, often paired with a bass boosted hit or a frozen reaction shot. Like the To be Continued arrow, it became shorthand in edits for a moment that has already ended badly.
